The company attributed the performance to a record level of natural gas equivalents and increased sequential production from oil and natural gas liquids to 20% of Quicksilvers overall production stream

Continued strength from Quicksilver's Barnett Shale properties, combined with our Horn River Basin natural gas project, fueled record second quarter production results, said Quicksilver CEO Glenn Darden. The company's liquids production is one-fifth of our total production stream, which is having a disproportionately positive impact on returns and cash flow.

Looking ahead, the company expects third-quarter production volumes to rise 3% to 425 million to 435 million cubic feet equivalent per day.
